The Acudor DW-5040 is designed specifically for installation in drywall walls and ceilings after drywall has been installed. The flange of the door is a textured galvanized steel taping bead with pre-punched holes. Drywall compound is applied over the beading at the same time the drywall joints are finished. When the application is completed, only the door panel remains exposed. Our unique concealed hinge and screwdriver operated cam latches allow the door panel to operate freely with no binding, sagging or distortion.
